Coding work in PHP and Javascript with MySQL

I need some help with completion of some coding in Javascript and PHP for an internal system plus a website upgrade. Underlying database is MySQL. I would like to hire 2 experienced Javascript&PHP programmers who can work as a team together with me for 2 weeks, with frequent daily video meetings on Skype or Google Hangout or similar. We'll start with a tour of the existing software and description of what modifications are required. You are expected to be able to understand the existing code quickly and start working on modifying it and then uploading and testing the updated modules right away one by one. Please bid a fixed price for 2 coders for 2 weeks with 6 days per week and 8 hours per day. Preferred start date: 8 November.
